The return value of require is usually not a reasonable thing to rely on, aside from it being true. The first time requiring a file, it will return the value of the last statement in the file. The second time requiring a file, it will return a simple true value. Mojo was bypassing this problem by deleting the %INC entry for the file, forcing it to always be loaded again. But the new module_true core feature will cause require to always return a simple true value rather than the last statement in the file. This does not apply to do though. Switch to using do to be compatible with code using the new feature.

There was a problem hiding this comment.
Generally I approve, however I wonder if in the test it should explicitly load the module_true pragma rather than the feature bundle, and if it should do so after Mojolicious::Lite. That way if some "fixup" is ever attempted in either of those places we'd still be explicitly testing the pragma not the generic scenario? Maybe both?
